Wow, I'm not sure how that option escaped my notice for all these years.
Of course it would be much more useful if it pulled the value from the
remote HEAD (but again, unless we use "-f" we are not contacting the
remote at all).

Agreed that the naming is bad.

If it's simply not present (which is the case now after "git remote
add"), then it might be reasonable for "git fetch" to use that as the
hint to fill it in. That would also make "git remote add -f" just work,
I believe.
It does mean that you can _change_ the value of origin/HEAD, but you
wouldn't be allowed to delete it without fetch trying to re-create it.
I suspect this is quite rare, but we might want an escape hatch config.
E.g., remote.origin.updateHEAD that can be set to one of:
- never; do not touch it
- create-if-missing; as discussed here
- always; update it on every fetch
And then it is just a question of what the default is. Currently it is
"never". I suspect most people would be happy with "always", but it does
break some existing flows. But perhaps "create-if-missing" is a good
medium.
